We should take a lesson from Singapore and use corporal punishment. The consequences for some of these people should be public caning in front of their peer group. Show the whole crowd what psychologically traumatizing pain looks like. Then see if any of them want to show some "attitude" in the future.

I’ve always agreed with Heinlein’s society in Starship Trooper. They had 2 forms of punishment: flogging and hanging. No prisons, no probation, no monitoring.
